Issue Description

The SIG9800 is sold as a suite of solutions. Materials such as AC-and-DC power supplies and circuit breakers may need to be configured on industry networks. This case describes how to connect power supplies and circuit breakers in redundancy mode to the SIG9800 and S2600.

Handling Process

1. Devices
ELTEK power supply, circuit breaker, T8000, SIG9800, bypass, and S2600
2. Circuit breaker introduction
A circuit breaker has two independent control modules, as shown in the preceding figure. Each control module has two input channels, that is, input 1 and input 3. Input 1 matches output 1 to 7, and input 3 matches output 9 and 10. The following table describes the maximum current that each output supports. Based on this table, provide different current output for devices with different power requirements.

3. Power supply connections on an SIG9800
The T8000 and SIG9800 both require 50 A power input of each channel, and the bypass requires 5 A power input of each channel. An ELTEK power supply converts AC power to DC power and transmits the DC power to the circuit breaker for power distribution. Power supplies of each device must connect to the two control modules of the circuit breaker to implement power supply redundancy.
